Filed:

Jul 20, 2012

Appl. No.:

13/554781

Inventors:

Sung K. Lee - Euless TX, US
Charles L. Thomas - Salt Lake City UT, US

Assignee:

University of Utah Research Foundation - Salt Lake City UT

International Classification:

B29C 33/42

US Classification:

600573, 604272, 606167, 604173, 264219, 249127

Abstract:

The present invention provides a method for creating a beveled needle or a blade. The method employs a side wall surface of an angled post as a base to control beveled tip geometry. The invention provides needles, microneedle arrays, blades and microblade arrays with sufficient sharpness and toughness.

International Classification:

A61F 2/16

Abstract:

A method and system provide an ophthalmic device including an optic and a haptic. The optic includes at least one optical material having a first Young's modulus. The haptic is coupled with the optic. The haptic includes at least a second Young's modulus greater than the first Young's modulus and less than 1.8 GPa. Thus, the haptic is stiffer than the optic, but more flexible than a material such as polymethyl metacrylate (PMMA).

International Classification:

B25J 9/16

Abstract:

Systems and methods for controlling a swarm of mobile robots are disclosed. In one aspect, the robots cover a domain main of interest. Each robot receives a density function indicative of at least one area of importance in the domain of interest, and calculates a velocity vector based on the density function and a displace vector relative to an adjacent robot. Each robot moves to the area of importance according to its velocity vector. In some aspects, the robots together perform a sequence of formations. Each robot mimics a trajectory as part of its performance by switching among a plurality of motion modes. Each robot determines its next motion mode based on a displacement vector relative to an adjacent robot.

Appl. No.:

14/833410

Inventors:

- BASEL, CH
SUNG KYU LEE - EULESS TX, US

International Classification:

A61F 2/16

Abstract:

A capsular ring includes substantially circular anterior and posterior surfaces each defining a central void of the capsular ring, at least a portion of the anterior and posterior surfaces being substantially flat. The capsular ring further includes an exterior surface extending around the circumference of the capsular ring between the anterior surface and the posterior surface, wherein there is a sharp transition between the exterior surface and both the anterior surface and the posterior surface. The capsular ring further includes a plurality of orifices spaced circumferentially around the exterior surface and a plurality of haptics spaced circumferentially around the exterior surface and extending outwardly from the capsular ring; each of the plurality of haptics being configured, upon insertion of the capsular ring into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag of the patient's eye.

Appl. No.:

14/834130

Inventors:

- BASEL, CH
SUNG KYU LEE - EULESS TX, US

International Classification:

A61F 2/16

Abstract:

A capsular ring for insertion into a capsular bag of a patient's eye includes an anterior ring defining a first opening and having a first cross-sectional width and a posterior ring defining a second opening and having a second cross-sectional width. A diameter of the first opening is greater than a diameter of the second opening, and the second cross-sectional width is greater that the first cross-sectional width. The capsular ring further includes a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.

International Classification:

H04R 7/14
H04R 7/18

Abstract:

A micro electro mechanical system (MEMS) microphone includes a base; a MEMS die disposed on the base; and a cover coupled to the base and enclosing the MEMS die. The MEMS die includes and diaphragm and back plate and posts extend from a first periphery of the back plate. The diaphragm is free to move within a boundary created by the posts. A front volume is formed on a first side of the diaphragm and a back volume is formed on a second side of the diaphragm between the diaphragm and the cover. A plurality of openings extend through the diaphragm about an outer periphery of the diaphragm, the openings being effective to mitigate noise.
